    3M Obsidian Automotive Window Film

    3M Obsidian Automotive Window Film is a metal-free, entry-level dyed film that is unlike any other dyed film. 3M uses its patented “Infuse Technology” to embed a series of dyes into the polyester film. For the consumer, that means richer color, increased performance, and greater color stability. Backed by a national lifetime warranty, Obsidian is perfect for the consumer who seeks performance at a budget-friendly price.

    Data shown is the estimated performance of film applied to ¼” (6mm) thick, 73% VLT automotive green glass. Data is for reference only.

    *IRR: Percent of solar infrared energy in the 900 – 1,000 nm wavelength range that is rejected by the film. Measurement is made of film with liner alone (i.e. no glass).

    **IRER: Percent of solar infrared energy that is rejected over the wavelength range from 780 – 2,500 nm. IRER takes into account the transmitted and absorbed IR energy that will be reradiated into a car. Data shown is for the performance of film applied to glass.

    Benefits of 3M Obsidian

    Stay Cool

    The Obsidian Series incorporates 3M’s patented “Infuse Technology” that provides better durability than many dyed films due to the bonding of the dye particles into the film. These films also provide strong heat rejection, low reflectivity and protection from ultraviolet (UV) rays, thereby enabling you to stay cool. Obsidian Series rejects up to 60% of the total solar energy coming through your windows.

    Stay Connected

    The Obsidian Series is a non-metallized window film that won’t interfere with mobile devices, GPS or satellite radio reception.

    Reduce Glare

    The Obsidian Series reduces up to 93% of the glare from blinding sunlight, allowing you to see better and concentrate more on driving.


    Increase privacy for you and your valuables with the Obsidian Series, available in tint levels that can block up to 95% of visible light into your vehicle.

    Superior UV Protection

    Blocking up to 99.9% of UV light, the Obsidian Series provides a total Sun Protection Factor (SPF) of up to 1,000. This helps provide vehicle occupants with significant protection from harmful UV rays.

    Limited Lifetime Warranty

    The Obsidian Series is backed by a limited lifetime warranty, one of the most comprehensive warranties you can get. Sold and installed by professional 3M Authorized Dealer Installers, our films are durable, designed to last and virtually maintenance-free.
